Overview

Investment Approach

BlackRock MuniHoldings Fund, Inc.’s (MHD) (the 'Fund') investment objective is to provide shareholders with current income exempt from federal income
taxes. The Fund seeks to achieve its investment objective by investing at least 80% of its assets in municipal bonds exempt from federal income taxes
(except that the interest may be subject to the federal alternative minimum tax). The Fund invests, under normal market conditions, at least 75% of its
assets in municipal bonds rated investment grade and invests primarily in long-term municipal bonds with a maturity of more than ten years at the time of
investment. The Fund may invest directly in such securities or synthetically through the use of derivatives.

No assurance can be given that the Fund's investment objective will be achieved.
